2 DESCRIPTION
2.1 DriveThe machine is rear wheel drive.
The rear axle is equipped with a hydrostatic trans-
mission with infinitely variable forward and re-
verse gear ratios.
The rear axle is also equipped with a differential to 
facilitate turning.
Front mounted tools are driven by drive belts.
2.2 SteeringThe machine is articulated. This means that the 
chassis is divided into a front and a rear section, 
which can be turned in relation to each other.
The articulated steering means that the machine 
can turn around trees and other obstacles with an 
extremely small turning radius.
2.3 Safety systemThe machine is equipped with an electrical safety 
system. The safety system interrupts certain activ-
ities that can entail a danger of incorrect manoeu-
vres. For example, the engine cannot be started if 
the clutch-parking brake pedal is depressed.
The operation of the safety system must 
always be checked every time before 
use.
2.4 Controls
2.4.1 Implement lifter, mechanical (3:C)

on public roads.
4 STARTING AND OPERATION
The machine may not be operated un-
less the engine casing is closed and 
locked. Risk of burns and crushing in-
juries.
4.1 Filling with petrolAlways use lead-free petrol. You must never use 2-
stroke petrol mixed with oil.
The tank holds 12 litres. The level can easily be 
read through the transparent tank.
NOTE! Ordinary lead-free petrol is a perishable 
and must not be stored for more than 30 days.
Environmental petrol can be used, i.e. alkylate 
petrol. This type of petrol has a composition that is 
less harmful for people and nature.
Petrol is highly inflammable. Always 
store fuel in containers that are made 
especially for this purpose. 
Only fill or top up with petrol outdoors, 
and never smoke when filling or top-
ping up. Fill up with fuel before starting 
the engine. Never remove the filler cap 
or fill with petrol while the engine is 
running or still warm.
Never completely fill the petrol tank. Leave an 
empty space (= at least the entire filler tube plus 1 
- 2 cm at the top of the tank) to allow the petrol to 
expand when it warms up without overflowing. 
See fig. 9.
4.2 Checking the engine oil level
On delivery, the crankcase is filled with SAE 10W-
40 oil.
Always check the oil level before use to ensure it 
is correct. The machine should be standing on 
level ground.
Wipe around the dipstick. Unscrew and 
pull it up. Wipe the dipstick. 
Push the dipstick down completely and screw into 
place. 
Unscrew and pull the dipstick up again. Read off 
the oil level.
Top up with oil to the “FULL” mark if the oil level 
is below this mark. See fig. 10-12.The oil level must never exceed the “FULL” mark. 
This results in the engine overheating. If the oil 
level exceeds the “FULL” mark, the oil must be 
drained until the correct level is achieved.
4.3 Level check, transmission oil
On delivery, the crankcase is filled with SAE 10W-
40 oil.
Always check the oil level before use to ensure it 
is correct. The machine should be standing on 
level ground.

5 MAINTENANCE
5.1 Service programmeIn order to keep the machine in good condition as 
regards reliability and operational safety as well as 
from an environmental perspective, STIGA’s Ser-
vice programme should be followed.
The contents of this programme can be found in 
the attached service log.
Basic service
 must always be carried out by an au-
thorised workshop.
First service and intermediate service
 should be 
carried out by an authorised workshop, but can 
also be carried out by the user. The content of this 
can be found in the service log and the actions are 
described under “4 STARTING AND OPERA-
TION” as well as below.
Servicing carried out at an authorised workshop 
guarantees professional work using genuine spare 
parts.
At each basic service and intermediate service car-
ried out at an authorised workshop, the service log 
is stamped. A service log presenting these services 
is a valuable document that improves the ma-
chine’s second-hand value.
5.2 PreparationAll service and all maintenance must be carried out 
on a stationary machine with the engine switched 
off.
Prevent the machine from rolling by al-
ways applying the parking brake.
Stop the engine.Prevent unintentional starting of the 
engine by disconnecting the spark plug 
cable(s) from the spark plug(s) and re-
moving the ignition key. 
5.3 Tyre pressureAdjust the air pressure in the tyres as follows:
Front: 0.6 bar (9 psi).
Rear: 0.4 bar (6 psi). 
5.4 Changing engine oilThis section contains tables covering the different 
engines that are included in STIGA’s Pro range. To 
facilitate reading, mark the data that applies to the 
relevant machine/engine.
5.4.1 Change intervals
The table below states hours of operation and cal-
endar months. Carry out the relevant action at 
whichever occurs first.

Replace the fuel filter after 1,500 hours of opera-
tion.
Check for fuel leaks once the new filter has been 
installed.
5.6 Belt transmissionsAfter 5 hours of operation, check that all the belts 
are intact and undamaged.
5.7 SteeringThe steering must be checked/adjusted after 5 
hours of operation and thereafter after 100 hours of 
operation.
5.7.1 Checks
Briefly turn the steering wheel back and forth. 
There must be no mechanical clearance in the 
steering chains.
5.7.2 Adjustment
Adjust the steering chains if required as follows:
1. Put the machine in the straight-ahead position.
2. Adjust the steering chains with the two nuts, lo-
cated under the central point. See fig. 26.
3. Adjust both nuts by the same amount until there 
is no clearance.
4. Test drive the machine straight forwards and 
check that the steering wheel is not off centre.
5. If the steering wheel is off centre, undo one nut 
and tighten the other.
Do not over-tighten the steering chains. This will 
cause the steering to become heavy and will in-
crease wear on the steering chains. Machine Oil volume, approx.

5.8 Battery
If acid comes into contact with the eyes 
or skin, this can cause serious injuries. 
If any part of the body has come into 
contact with acid, rinse immediately 
with copious amounts of water and seek 
medical assistance as soon as possible.
The battery is a valve-regulated battery with 12 V 
nominal voltage. The battery fluid does not need to 
and cannot be checked or topped up. The only 
maintenance that is required is charging, for exam-
ple after extended storage.
The battery must be fully charged be-
fore being used for the first time. The 
battery must always be stored fully 
charged. If the battery is stored while 
discharged, serious damage will occur. 
5.8.1 Charging with the engine
The battery can be charged using the engine’s gen-
erator as follows:
1. Install the battery in the machine as shown be-
low.
2. Place the machine outdoors or install an extrac-
tion device for the exhaust fumes.
3. Start the engine according to the instructions in 
the user guide.
4. Allow the engine to run continuously for 45 
minutes.
5. Stop the engine. The battery will now be fully 
charged.
5.8.2 Charging using battery charger
When charging using a battery charger, a battery 
charger with constant voltage must be used.
Contact your dealer to purchase a battery charger 
with constant voltage.
The battery can be damaged if a standard type 
battery charger is used. 
5.8.3 Removal/Installation
The battery is placed under the engine casing. Dur-
ing removal/installation, the following applies re-
garding connection of the cables:
• During removal. First disconnect the black ca-
ble from the battery’s negative terminal (-). 
Then disconnect the red cable from the battery’s 
positive terminal (-).
• During installation. First connect the red cable 
to the battery’s positive terminal (+). Then con-
nect the black cable to the battery’s negative ter-
minal (-).
If the cables are disconnected/connect-
ed in the wrong order, there is a risk of 
a short-circuit and damage to the bat-
tery.If the cables are interchanged, the gen-
erator and the battery will be damaged.
The engine must never be driven with 
the battery disconnected. There is a risk 
of serious damage to the generator and 
the electrical system.
5.8.4 Cleaning
If the battery terminals are coated with oxide, they 
should be cleaned. Clean the battery terminals with 
a wire brush and lubricate them with terminal 
grease.
